I'd say, more than anything, listen to my opinion, and robm's on this, I certainly hope he gives his input.
Both of us are big on cars, to say the least.
And let me tell you, at $1000, I would not do it.
Actually, price aside, I would not do it.
If it's hard to start, it doesn't run fine.
There are many things that could be wrong with this car that you don't know about.
If it were more desirable, if it was something you were quite interested in, if this was a rare opportunity, I would say go get it checked out by a mechanic.
First off, get underneath the Dang thing, lift up the carpet, etc, and look for rust.
Rust is my personal HUGE RED FLAG, I will NOT approach a vehicle with any level a rust beyond a dime spot.
Also, Bondo. Bondo keeps junkers lookin' decent.
Look for Bondo.
Tap parts of the body, grab a magnet and feel for areas that DON'T pull, etc.
There are lots of guides to finding Bondo on a car.
If it's got more than a patch or two, or anything large, I'd avoid it.
"Runs Good" doesn't mean much, and when you hear it from the person selling, it means absolutely nothing.
Run it, Drive it, Listen to it. Feel it shift, feel it's power, feel it turn, and brake.
Determine for yourself how well it drives, and if you're truly interested, I'd trust a mechanic to tell me of anything I can't see for myself.
(Checking the coil on an older vehicle is the first thing I'd do myself, and checking the compression depending on the vehicle. Some I'd let the mechanic do that.)
Also look at it's known problems.
No A/C, why? No parking break, what's wrong with it?
Also, this is me personally, but, Emissions.
*Can'tSayThisOnTV* emissions, I hate emissions, and emissions hate you.
'77 means that thing has to meet emissions to be legal to drive.
And if you buy it, get it checked, and you can't legally drive it, you're SOL.
You've just bought a vehicle, and now you need to pay for repairs before you can even drive it legally.
Emissions piss me off.
Now a bit about El Camino's.
'77, means you've got either a 350, 400, or 454 cubic inch.
Now, I REALLY doubt that's thing's rocking a big block 454.
Chances are, sadly, it's the 350.
And actually, being a '77, it COULD have the 305 they added in '76.
FIND OUT THOUGH.
If it's the 454, and the compression's good, I'd hop on it, because the big block is money even if the rest of the car is flax.
FIND OUT THE MODEL.
Yes, it's an El Camino, and it's a '77.
FIND OUT IF IT'S THE CLASSIC!
If you gave us a picture of the FRONT of the Dang thing I could already tell you, but with just what I see there, I can't determine it.
If it's the Classic, it's worth more, not a lot more, in fact, almost negligibly more, but it is worth more.
Honestly? I say that as a parts car.
The Classic had different headlights, etc, that are ever so slightly more obscure than the normal ones, meaning they're worth nickels and dimes more.
Plus, it could be an SS.
I can't tell if it is.
It's probably not.
But it could be.
It's probably not though.
But let's "Pretend" this IS the SS, has a 454, runs good.
Then $1000 is a steal even if the body ain't too great.
But seriously, being the dick that I am, I wouldn't touch it just because of emissions.
I don't like that.
I cream for speed.
And I don't want no catalytic converter or fuel injection.
I like Carbs, tail-pipes without mufflers, and the smell of gas on a hot day.
